Geological Significance

1 geosite of international geological significance
The Qinling orogenic belt is one of the most typical geosites in the geopark, it is a typical composite continental orogenic belt in China and also a main combination belt that forms the integrated mainland of China, which traverses east and west and lies in the center. It has become the natural boundary of geology, geography, ecology, climate, environment and even humanities between the north and south of China, which has the uniqueness of global geological commonness.

The scale of landslide ranks third in the world (after the Usoi landslide in Tajikistan and the Waikaremoana landslide in New Zealand). Its landslides have complete landform and morphology, such as landslide free surface, collapse accumulation, barrier dam, barrier lake, collapse cave and so on.

5 geosites of national geological significance
The geopark retains complete Quaternary glacial relics, which is of great significance to the study of Quaternary paleoclimate evolution and glaciation in China and even East Asia.

Heihe rift zone is the largest graben type tectonic basin in China. It has become an important base of Quaternary Geology and neotectonic movement in China due to its typical fault block tectonic landform, huge geomorphic contrast, Cenozoic sedimentation with a thickness of 7000m and strong neotectonic movement.

The fault from Houzhenzi to Shaliangzi to Shagoujie is a suture zone formed by collision between the North China’s Plate and the Yangtz Plate, which consists of rock formations, slices and faults of different periods, properties, and types. It is typical in the geoheritage of plate tectonics.

The big piedmont fault in the northern margin of Qinling Mountain is the scarpside of Weihe graben. It has been active since the late Cretaceous with a fault distance up to 13 km. The Weihe rift belt on its north side is an intracontinental faulted depression basin filled with huge thickness, which has international research significance.

Lantian ape man is a Homo erectus fossil discovered in China, which is second only to Yuanmou ape man (1.7-1.8 million years ago). It is one of the representatives of late ape man and the earliest surviving Homo erectus in northern Asia.
